OS3 - Characters
 

My Virus TI desktop with OS3 - the first and last characters 'analog boost' and 'stereo width' (or somesuch), show up and have working controls and parameters. All the other 'characters' are greyed out and don't do anything in Virus Control.
On the desktop unit itself, the characters are listed under knob 1, but there's nothing showing on knobs 2 and 3. Is anyone else getting this problem?
